Environment

NFA 9.3.x for Windows.

Cause

Migration of database fails because of Mysql Service crash during ahtflows table creation.

Errors in Mysql logs:

mysqld got exception 0xc0000005 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=8388608
read_buffer_size=16777216
max_used_connections=1
max_threads=200
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 731519 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x2cc07900f0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Resolution

The root cause of this issue is figured out to be a VC++ Package on OS.

Download Microsoft Visual C++ 2013 Redistributable (x64) 12.0.30501. from the below link:https://support.microsoft.com/en-us/kb/3179560
Revert back to previous 9.3.3 setup. You have to reinstall NFA 9.3.3 and load the database of harvester database which you have taken backup before upgrading to 9.3.6.
Make sure everything is running good in 9.3.3
Install the missing Microsoft VC++ Redistributable.
Restart the upgrade.

This time the upgrade should go good with out any errors.
